As­sum­ing that you mean “are full mem­bers on the al­ign­ment fo­rum”, the an­swer is no. As soon as any of your con­tent ever gets pro­moted to the Align­ment Fo­rum, you can start ac­cru­ing AF karma, and can start vot­ing on al­ign­ment fo­rum con­tent with your AF karma (i.e. your votes will change the vote-to­tals).

(the ac­count databases are shared, so ev­ery LW user can log in on al­ign­ment fo­rum, but it will say “not a mem­ber” in the top right cor­ner)

Ah, sorry! I think I didn’t test the oAuth lo­gin on al­ign­ment­fo­rum.org. We prob­a­bly have a refer­ence to the LessWrong.com URL some­where left in that code, so that’s where it for­wards you. Will fix it ASAP.
